Telnet is a protocol for bidirectional interactive text-oriented communication with remote hosts via virtual terminals. It is defined in [RFC 854](http://tools.ietf.org/html/rfc854). Telnet provides no inherent security and so is becoming less commonly supported. On modern UNIX-like systems it is usually replaced with more secure and flexible [SSH](/tags/ssh/info) protocol.
